Slightly off topic, but Claude Code (and likely other models/harnesses) are incredibly effective at Nix. It can trivially self-verify, without side effects, which is a perfect match for an LLM.

If you've ever been put off by the difficulty of the language, it's worth checking it out again with AI assistance.

I've one-shotted custom distributions built with Nix using AI. It's crazy how well AI and Nix fit together.

I also love how with the right system prompt they can pull in tooling for what they currently need via a nix shell

Agreed, Claude has helped a lot with this project, and being able to iterate without side effects for system configuration changes is really a game changer for agents.

Earlier quoted context omitted.

What quant are you using, and what tps are you getting with K3?

The FP8 version from DeepSeek themselves [0], around 1800 tps prefill and 45 tokens per second decode. I’ve been running a custom VLLM image with b12x as well as nvfp4_ds_mla. I would say it’s quite fantastic in day to day, I use it mostly in Hermes and sometimes for coding. I have qwen 3.6 27b on an rtx 6000 pro as well so I use that as a workhorse in pi with DS as a reviewer/planner. [0] https://huggingface.co/deep…

Thanks - yeah, sorry, I mis-read that as you using both DS and K3...

I got curious one Saturday and ported our monorepo to use Nix for build and test and release. It was a very pleasant process. I had to put aside to tackle more pressing things but I'm all in on using Nix in that capacity.

Absolutely. Running NixOS is a wonderful experience for this reason. NixOS + LLMs make it a breeze to make changes to your system, install and configure new software, and debug issues. Having every aspect of your system defined in a git repo is the perfect fit for agent harnesses.

I'll admit, even with LLMs to help, the Nix language and NixOS did have a rather steep learning curve, because it's quite different from anything I'd experienced before. But after getting the hang of it, I can't imagine going back to a "normal" OS and I'm very happy I put in the time to get over the initial friction.

Same for Bazel. It has historically been a very difficult to understand/adopt/rollout tool for a lot of engineering orgs but is going swimmingly for the organization I currently work for.
